Most critics like Sunny, and the praise gathers in two places: Rashida Jones, whose surly, grounded performance several reviews credit with holding the series together, and the look of it, a retrofuturistic Kyoto whose production design even the least enthusiastic reviews call vivid and immersive. Joanna Sotomura’s warm voice work as the robot draws separate notice, as does a tone the reviews describe as dark, funny and quietly sinister, with a real interest in grief under the android comedy.
The reservations are about the storytelling. Several critics find the plot scattered and the protagonist thin, and more than one calls the finale weak. The spread is wide: The Guardian gives it five stars and calls it the most original show of the week, while IndieWire finds it too muddled for its treatment of grief to land, and The Hollywood Reporter thinks the characters are kept at a distance. Variety admires the world-building but finds it unsatisfying as a mystery. Even the dissenters like how it looks; the disagreement is over whether the story holds.
